ABSTRACT:
A method of compactly storing digital data includes the steps of sequentially entering a plurality of digital data entries into a shift register having a plurality of stages and summing successive groups of data entries as they are outputted from the shift register to produce singly compressed data entries that are subsequently entered into a second shift register. Sets of singly compressed data entries which are outputted from the second shift register are again added to obtain doubly compressed data entries which are entered into a third shift register. This process continues until a sufficient number of shift registers have been employed to accommodate all of the expected data entries.
